+Overview:
+"""""""""
+
+The '``ptrtoaddr``' instruction converts the pointer or a vector of
+pointers ``value`` to the underlying integer address (or vector of integers) of
+type ``ty2``. This is different from :ref:`ptrtoint <i_ptrtoint>` in that it
+only operates on the index bits of the pointer and ignores all other bits.
+``ty2`` must be the integer type (or vector of integers) matching the pointer
+index width of the address space of ``ty``.

I think the sentence fits better into the arguments sections which currently
says "which must be an :ref:`integer <t_integer>` or a vector of integers
type." without specifying which integer type specifically it has to be.
